INVENTOR E. M. BUCHACH ATTORNEYS'Y Patented May 31, 1938 UNITED STATES PATENT OFFICE WINDOW CONSTRUCTION Application December 30, 1935, Serial No. 56,734

4 Claims.

This invention appertains to window constructions of the type wherein the sliding sashes are arranged to be swung inwardly relative to their window frame for ventilating purposes and to facilitate cleaning both sides of the glass panes of the sashes.

The present invention generally seeks to improve that form of window shown in my prior Patent No. 2,038,266, issued to me April 21, 1936, whereby a durable, efiicient, and fool-proof window will be had, which will be easy to operate by the ordinary housewife, and which will be acceptable to the trade both from a manufacturing and installation standpoint.

Another primary object of my invention is to improve the construction of fixtures for sliding and swinging window sashes, whereby the use of springs and other complicated mechanism which might be subjected to undue wear and breakage, is eliminated, and whereby ease of operation is insured.

Another object of my invention is to provide improved fixtures for sliding and swinging sashes, whereby an ordinary window can be readily converted into a combined sliding and swinging window. I

Another important object of my invention is to provide novel means for forming the tracks and weather strip stops for the upper and lower sashes, whereby the same can be folded from a single strip or piece of sheet metal.

A further object of my invention is to provide novel slide members mounted in the channels of the side guides for pivotally supporting the sashes, with novel sash cord-operated catches for engaging in grooves formed in the edges of the tracks and window frame, when the sashes are in a predetermined raised position and swung into a room, so that accidental sliding movement of the sashes is prevented.

A further salient object of my invention is the provision of manually operated latches carried by the sashes adapted to move through said grooves when said latches are actuated, to permit the swinging of the sashes into their vertical or angular positions, the latches providing automatic means for releasing the catches when the sashes are in their vertical planes, to permit intentional raising and lowering of the sashes.

A further important object of my invention is the provision of wear and stop guide plates carried by the slide plates for the sashes arranged adjacent to the swinging sash cord-operated catches for partially engaging the manually operable sash latches, so as to reduce undue wear on the sash guides and for eliminating objectionable click as the catches and latches ride past the grooves in the guides.

A further object of my invention is the provision of means for detachably and pivotally connecting the sashes with the slide plates, whereby ease of operation of the swinging sashes is assured without danger of accidental displacement of the sashes from the slide plates.

With these and other objects in view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a longitudinal section through a window constructed in accordance with my invention, showing the sashes in dotted lines in their fully swung-open position to facilitate the cleaning of the glass panes thereof.

Figure 2 is an enlarged, fragmentary, front elevation of a window constructed in accordance with my invention, with the bottom sash in its partially raised position ready to be swung into a room. a

Figure 3 is a longitudinal section taken on the line 3-3 of Figure 2 looking in the direction of the arrows, with the view contracted and the intermediate part of the sash and frame eliminated, the figure illustrating one form of manually operated sash latch and one form of hingedly Figure 5 is an enlarged fragmentary view looking toward the face of one of the novel guide pieces, with the slide plate therein and held against movement by the sash cord-actuated catch, the sash being in its swung-open position.

.Figure 6 is a detail section through the bottom of a sash similar to the lower part of Figure 3, illustrating another form of means for pivotally and detachably connecting the sash to a slide plate.

Figure '7 is an enlarged, transverse, sectional view through one of the novel tracks and weather strip stops for the sashes, a part of one of the slide plates and its associate mechanism being shown in one of the channels of the guide, the slide plate and its associated mechanism being of a modified form, the section through the slide plate and its associate mechanism being taken substantiallyon the line 1---! of Figure 8 looking in the direction of the arrows.

Figure 8 is an enlarged fragmentary view of one of the guide tracks and weather strip stops, illustrating the novel wear and guide plate for the latch and sash catches connected with the slide plate, the latch for the sashes being shown in cross-section.

Figure 9 is a view similar to Figure 4, illustrating the modified sash latch.

Figure 10 is an enlarged, fragmentary horizontal section taken through the window on the line lillfl of Figure 2, looking in the direction of the arrows.

Figure 11 is an enlarged, fragmentary, detail vertical section taken on the line H-ll of Figure 10, looking in the direction of the arrows.

Figure 12 is a detail fragmentary view taken on the line l2--l2 of Figure 11, looking in the direction of the arrows, showing the rigid latch lug.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter F generally indicates a window frame for the sliding and swinging top and bottom sashes Ill and H. The window frame is of the ordinary construction and includes the side stiles I2, the lintel l3, and the sill l4.

Secured to the inner faces of the stiles I2 are my novel guides and weather strip stops l5 for the sliding and swinging sashes.

In my patent heretofore mentioned, the tracks and weather strip stop beads for the sashes were of an integral structure and extruded, and in the present construction, the same are preferably formed from a single strip of sheet metal bent and folded into the desired shape. Thus, the metal is folded to provide channels "5 and I! for the upper and lower sashes l0 and H connected together by integral web 18, the sides of which extend beyond the adjacent walls of the channels to form flanges l9 and 26. One side wall of the channel I! below the flange 20 is folded to provide a guide flange 21 for the channel, and the opposite wall of this channel is bent in to form the opposite guide flange 22. The wall of the channel l6 opposite the flange I9 is folded intermediate its ends to provide a guide flange 23, and the extreme outer edge of this wall is' bent inwardly, as at 24, to form the bead or stop for the sash-carried weather strip.

The flanges l9 and 23 form a part of the channel [6, which acts as a guide for the slide plate 25 of the upper sash I0, while the flanges 2| and 22 form a part of the channel ll, which functions as a guide for the slide plate 26 of the lower sash ll. Obviously, this construction is duplicated on the other side of the window. All of the slide plates 25 and 26 are provided with pads 21 which fill up the space between the inner walls of the channels and the flanges 23, [9, 2|, and 22. This prevents the sliding plates from rattling and prevents the creeping of air up the channels.

The lower corners of the sashes l0 and II are provided with castings or fittings 28 for the reception of inwardly directed pivot pins 29 carried by the lower ends of the slide plates 25 and 26. As shown in Figures 1, 2, and 3, the pins 29 can have flattened sides to permit the sliding thereof in the restricted neck entrances 30 of the bearing openings 3|.

When the window sashes are in a horizontal position, the pins 29 will register with the restricted neck entrances and allow the sashes to be pulled out of the bearing openings, so thatthe sashes can be entirely disconnected from the slide plate. This forms a convenient means for assembling the sashes in the window frames.

In lieu of utilizing flattened pins and restricted neck entrances, I can provide slotted bearing grooves 32, as shown in Figure 6 of the drawings, and thus round pivot pins 33 can be carried by the slide plates 25 and 26 and slipped directly in the grooves from any position.

In order to hold the round pivot pins in place machine screws 34 can be threaded into the castings or fittings carried by the corners of the sashes with the heads thereof overlying the pivot pins. This reduces all hazard of the sashes being accidentally disconnected from the slide plates by a housewife. The side edges of both sashes have rigidly secured thereto metal wear strips 35, which are adapted to fit closely against the slide plates 25 and 26 when the sashes are in their vertical positions.

The sashes and the slide plates can be balanced in any preferred manner, and in the present instance I have illustrated sash cords 36 and 31 for the upper and lower sashes respectively, and these cords can be trained over suitable pulleys (not shown) and their outer ends provided with the window weights. The inner ends of the sash cords 36 and 31 are provided with eyes 38, into which are adapted to be placed the bills of hooks 39. These hooks 39 are associated with the slide plates in a novel manner, which will be later described.

Referring back to the window frame, it will be noted that the inner faces of the stiles are provided with outwardly flared guide grooves 40, the inner restricted ends of which communicate with notches 4| formed in the flanges 22 and the side walls of sheet metal guides. The walls of the grooves 40 carry any preferred type of metal wear plates 4 which also function to give a finished appearance to the frame.

The grooves 40 and 4| are provided for the lower sash, as will be later described, and the connecting portion l8 of the guides with its flanges l9 and 20 are cut away to provide grooves 42. These grooves are arranged above the grooves 40' and 4| and are provided for the upper sash, as will also be later described.

Both the upper and lower sashes are provided with novel latches for holding the sashes in an upright position and against swinging movement. All of these latches can be constructed in the same manner, with the exception that the latches on one side of the sashes can be spring-pressed. I Figures 2, 3, and 4, I have illustrated these latches, and it is to be noted that each latch includes a rigid latch lug 44 and a sliding latch lug 45. The latch lug 45 extends through a slot 46 formed in the metal wear plate 35 on the side of the sash, and the lug 45 is movable toward and away from the rigid lug 44.

The sash edges are mortised or recessed in the rear of the wear plates 35 to receive a face plate 41, which can either be secured to the woodwork of the sash or to the inner edge of the wear plate 35. The rigid lug 44 can be anchored to or formed directly on the wear plate 35, as shown in Figure 12.

The movable or sliding latch lug 45 is carried by a movable latch plate or bolt 48 arranged on the inner face of-the wear plate 35, and the same is provided with a longitudinal slot 48 in which is placed a guide pin 49. v A coil spring is placed in the slot with its ends between the pin 49 and one Wall of the slot for urging the latch plate 48 downward, and the movable lug 45 away from the immovable lug,44. An operating handle 5|- extends out of the face plate 41 and beyond the front face of its sash, so that the same can be conveniently manipulated. Normally, the latch lugs 44 and 45 of the upper sash ride against the inner edge of the flange l9, and the lugs 44 and 45 of the lower sash normally ride against the inner edge of. the flange 22 to hold the upper and lower sashes against outward swinging movement.

In order to swing open the sashes, the sashes are raised until their rigid lugs 44 register with the grooves 40, 4|, and 42, at which time the handles 5| can be manipulated for moving the movable lugs 45 toward the rigid lugs 44, so as to lift the movable lugs into registration with the guide grooves. After the lugs have been raised, the lugs 44 and 45 can be moved through the grooves and the sashes swung out.

It is highly desirable to hold the slide plates 25 and 25 against movement when the sashes are in their swung-open position, and hence I have provided novel catches 52 for this purpose. These catches 52 are pivotally connected at their lower forward corners, by means of pivot pins 53, to the upper ends of the slide plates, and the upper forward ends of the catches are provided with laterally extending ears or detents 54.

The hooks 39 for the sash cords have their lower ends connected by means of pivot pins 55 to the catches 52 at one side of the pivot pins 53, and hence the sash cords with their weights normally tend to swing the catches on the pivot pins 53, and the detents 54 toward the flanges l9 or 22, as. the case may be. Thus, when the sashes are raised and swung to an open position, the detents will be swung into the grooves 4| or 42, as the case may be. Obviously, this will effectively hold the slide plates and the sashes against sliding.

When the sashes are swung to a closed position, the lugs 44 and 45 will ride into the flared entrances of. the grooves 40 or 42, and the lug 45 will be moved toward the lug 44 by the lower wall of the groove. As the sashes reach their vertical positions the lugs will strike the detents 54 and swing the catches 52 back, and the detents out of the grooves. This will allow sliding movement of the slide plates and sashes. When the lug 45 moves back to its normal position away from the rigid lug 44, entrance of the lugs into the grooves will be prevented.

In Figures '7, 8, and 9 I have shown a slightly modified and preferred form of the window sash latches, and in this form rigid and movable lugs 56 and 51 are provided, and the inner edges: of the lugs overlap. The outer edges of the lugs are bent laterally to form stops 58. The sliding lug 5! is carried by a latch plate 59, which is actuated by a thumbpiece or handle 50.

In order to prevent Wear on the metal guides and to eliminate objectionable click as the window latches ride past the notches, I provide a novel guide and wear plate 6|, which is clearly shown in Figure 8. This guide and'wear plate BI is rigidly secured by means of. pins 62, with the upper ends of the slide plates, and the bottom portions of the wear and guide plates lie on the inner face of the slide plates and are provided with outwardly extending right angular wear flanges 63.

As illustrated in Figures '7 and 8, the wear flange 53 rides against the inner edge of the flange I9 or 22, as. the case maybe, and this flange 63'is so disposed as to form a stop for the swinging slide plate latches when the same are swung into the grooves.

When the sashes are in their vertical positions with the movable latch lugs 51 away from the rigid latch lugs, the same lie between the catches of the slide plate and the inner face of. the wear and guide flange 63. Thus, the latch lugs do not engage the walls of the channels of the guide members, and hence do not click against the inner ends of the walls of the grooves. This is an important feature and facilitates the ease of raising and lowering the sashes.

By referring to Figure 1, it will be noted that when the sashes are raised and then swung to their extreme open position, the lower sash rests against the sill adjacent to its outer end, and the top sash rests on top of the lower sash. By this arrangement, an efiective rest is formed for the sashes without imparting undue stress on the slide plates, and hence breakage of. the sashes and their fixtures is eliminated. When the sashes are in their full open positions, the opposite faces of the window panes can be easily cleaned.

The lower sash is also provided with a ventilating position, and to permit the same to be swung into such position, the inner faces of the stiles i2 of the window frame and the adjacent portion of the metal guides are grooved, as at 55. These grooves terminate short of the front edge of the window frame.

When it is desired to ventilate a room without creating any draft, the lower sash is slightly lifted, and when the sash latches are in correct position relative to the groove 55 the movable lugs are actuated and the sash is swung forwardly with the lugs riding in said grooves. The lugs engaging the front walls of the grooves prevents further movement of the sash. The lower end of the sash rests on the sill, and hence the entrance of the air into the room will be above the lower sash only.

From the foregoing description it can be seen that I have provided a window of the combined sliding and swinging sash type, which will operate efliciently under all conditions and which is substantially fool-proof.

The wear plates on the sides of the sashes. carry weather strips 65 formed of felt or the like, which are adapted to engage under the flanges 20 and 24 when the sashes are in their vertical position. This is similar to the construction shown in my mentioned co-pending application.

Changes in details may be made without departing from the spirit or the scope of this invention, but what I claim as new is:

1. In a window construction, a window frame including side stiles, upper and lower sashes, guide tracks secured to the inner faces of the stiles having spaced longitudinally extending channels, slide plates freely movable in the channels from one end thereof to the other, means pivotally connecting the lower ends of the sashes to the slide plates, the outer walls of the channels being provided with notches, pivoted catches carried by the upper ends of the slide plates, and sash cords connected with the catches at one side of theirpivots, whereby to normally swing the catches toward the outer walls of the channelsand into the notches when the slide plates are in a predetermined position.
